McGinty Mountain is a gabbroic mountain located in San Diego County, California near Jamul. Because of the gabbroic soil, the mountain supports numerous rare and endemic plant species, including half of the California's population of the Dehesa nolina (Nolina interrata). The mountain belongs to an ecological preserve collectively managed by The Nature Conservancy, the California Department of Fish and Wildlife, and the San Diego National Wildlife Refuge. The mountain is accessible through a 4.7 mi (7.6 km) long out-and-back hiking trail.
